Standard UF431T Ignition Coil

Ignition Coil for Kia Sorento

Standard UF431T is a coil-on-plug ignition coil built for 2003-2006 Kia Sorento applications. It uses a female connector, male terminals, and a 3-terminal layout to match the original electrical connection and restore consistent spark output.

Key Features

• Coil-on-plug ignition coil for direct replacement service
• Female connector with 3 male terminals
• Neodymium core for strong magnetic field generation and high-voltage output
• High-dielectric epoxy fill helps reduce air pockets and moisture intrusion
• Reinforced bobbin construction helps resist voltage flashover
• Built under OE manufacturing controls for consistent quality

Detailed Description

The Standard UF431T ignition coil is engineered for 2003, 2004, 2005, and 2006 Kia Sorento models. As a coil-on-plug unit, it delivers the voltage needed for reliable combustion at varying engine speeds, helping maintain smooth engine operation and stable ignition performance. The UF431T is also cross-referenced to Standard Ignition UF-431 for the same application.

Standard uses a neodymium core to generate a strong magnetic field and support high-voltage output across the operating range. The case is filled with high-dielectric epoxy under vacuum to help prevent internal voids, moisture intrusion, and thermal breakdown. Reinforced bobbins add durability against voltage flashover, which is important in demanding underhood conditions. This part number, UF431T, is a direct-fit ignition coil choice for Kia Sorento ignition service.

What It Helps Address

• Engine misfire caused by weak or failing ignition coil output
• Rough idle in 2003-2006 Kia Sorento models
• Hard starting related to inconsistent spark delivery
• Loss of power under load from ignition breakdown
• Check engine light concerns tied to ignition coil faults

Installation Notes and Tips

Verify connector style, terminal count, and engine application before installation. Inspect the coil boot, spark plug condition, and related wiring during service, since worn plugs or damaged connectors can affect ignition performance. For best results, replace any coil showing heat damage, cracking, or carbon tracking.

Quality Assurance

Standard manufactures this ignition coil as a tier I OE supplier with in-house engineering and design capabilities. Quality control is maintained throughout the manufacturing process, from component selection through finished product inspection.
